IBEFRleI-:RATOa SPECIFICATION forming part of` Letters Patent No. 287,691, vdated October 30, 1883.

' Application tiled May 25, 1883. (No model.)

To aZZ whom it may concern,

Beit known that I, GEROW KOONS, of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Refrigerators; and I do hereby declarefthat theVV following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters. of reference marked thereon, which form part of this specification, in which- Figure l is a front view of my improved refrigerator. Fig. 2 is a vertical section taken. longitudinally through the refrigerator, showing the internal structure thereof, also showing the automatic hinged gravitating,

door which separates the elevator-compartment from the refrigerator-compartment. Fig.

3 is a horizontal section through the refrigerator, taken in the plane a: x o n Fig. 2.

This invention relates to refrigerators whereinit is desired to keep food cool and to provide for families .living in what is known as dats My object is to combine an elevator with a refrigerator in such manner that the refrigerating-chamber may be arranged in the cellar or lowest story of a building and the casing or shelves be made vertically movable.

The invention consists in anovel combination of a trap-door with a refrigerating-chamber and a compartment in which are arranged one or more cases adapted to contain material to be refrigerated; also, in the combination of lock-boxes and reticulated sides therefor, which are vertically movable, with a refrigerator, all

of which will be fully understood from the following description whenl taken in connection .with the annexed drawings..

A designates a verticalshaft or hollow frame, which is subdivided by a vertical partition, B, forming two compartments, C U, which may extend from the cellar or any section of a building'through the several stories or liats to the highest story. The shaft or frame Av is provided with a refrigerating-compartment, C, on one side of the partition B, and located at or 1 near the bottom thereof is an ice-drawer, D,

applied between guides, in which drawer may be arranged a pipe-coil, D", through which water may iiow for the purpose of cooling it.

Above the ice-holding drawer I arrange, in

ywhen they are to them. This elevator is suspended bya rope or chain, which is passed over a pulley, p, and

over a pulley, p. This rope or chain is connected to a windlass or to any other device by means ofl which the cases G can be raised or lowered.

rIhecases are guided by strips xed to the side walls of the compartmentC, or in any other suitable way.

It is obvious that by my invention a single refrigerating-chamber will cool any number of cases or chests, each one of which'is a portused for anyiiat in a building. The reticulated lor gauze-wire sides and bottoms or shelves, g,

keep Out insects and also allow a free circulation of cold air. One refrigerating-chamy ber located in the cellar of a building will thus serve for a number of persons living 'in the different stories of the building.

For the purpose of preventing undue melting of the ice, I employ agravitating door, J, which is hinged at the end of an aperture through the partition-wall of the shaft A, and provided with a cam or trip, t. When the elevator is down, it Opens the saidvdoor, and when it is raised above this door the latter will Shut. I thus prevent in a great measure warm air from entering the ice-compartment when the elevator ,is raised above it.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is'- l y 1. The combination of a stationary refrigerator located in the basement of a building, a hollow shaft extending up through and com- -municating with the several stories'or flats of the building, a "dumb-waiter", composed of a series of chests having reticulated sides, doors G, and elevating mechanism for said waiter,

.all constructed and adapted to operate subable refrigerator in"y itself and adapted to be IOO 2 esmas;

ing with the several stories or flats of thc 15 building, a dumb-waiter composed of a series of chests having reticulated sides and bottoms, and elevating mechanism for said waiter, all

constructed and adapted to operate substantially in the manner and for the purposes dc- 2o scribed.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

GEROW KOONS.
